GB/T E6016-B3

AWS A5.5 E9016-B3                      

Description: R406 is a pearlitic heat-resistant steel electrode with a low-hydrogen potassium coating containing 2.5% Cr – 1% Mo.Both AC and DC can be used, and can be welded in all positions. The weldment must be preheated to 160 ~ 200°C before welding.

Application: Used for welding Cr2.5Mo pearlitic heat-resistant steel structures, such as high-temperature and high-pressure pipelines with operating temperatures below 550 ° C, synthetic chemical machinery, and petroleum cracking equipment.

Chemical composition of weld metal(%):

Mechanical properties of weld metal:

Diffusion hydrogen content of deposited metal: ≤4.0mL/100g (glycerin method)

X-ray inspection:  I grade

Recommended current:

Notice:

1. The electrode must be baked for 1 hour at around 350℃ before welding operation;

2. It is essential to clean up rusty, oil scale, water, and impurities on welding parts before welding.
